Re: WiFi? Timers!
It depends on what's required from the mechanism. A timer is good enough for allowing the bomber to get out of range. It may be good enough for attacking some specific event of significant duration such as a meeting. It wouldn't be good enough for targeting something less predictable such as someone passing a particular point; for that some sort of command system would be needed and this find suggests that that was the objective.
